Very touching drama, nice male and female leads and interesting other characters, especially Mr Oh the teacher - why do we never get teachers like this in real life? Covers many teen problems, not just romance, various sub-plots keep interest going. I thought it dragged in the middle, with lot of unoriginal school tropes. Can get too heavy, especially with male lead's struggles, one after another, but glad I stayed with it. Start of last episode I thought it had a credible conclusion but of course it then drowned in "corn" and tears, helped by the soulful music . This romantic type of drama, it seems this is inevitable. Need to be in sentimental mood for tears.
